When some projects have migrated from Subversion to Git, there were several tags that were treated as new commits, which shows a change in the whole project (code added/removed) when nothing really happened. For instance, in GNOME a lot svn tags were catched during the migration, but not all of them. svn tags in git repositories brings bad stats because double count commits, and in project with a lot history it may may involve several thousands of source of lines of code.
